Abstract (en)
The invention relates to a method for determining a geometrical parameter of an eye (20) of a subject, comprising the following steps: a) capturing at least two images of the eye (20) while the subject looks in two different gaze directions (GD) thanks to an image capture device (30), b) identifying, on each image, the image of the pupil (10) and/or the iris of the eye (20) and determining a geometrical feature of the image (I10) of the pupil and/or the iris linked to the shape of this image of the pupil and/or iris, c) determining said geometrical parameter of the eye (20) as a function of said geometrical features of the image (I10) of the pupil and/or iris determined for each image of said plurality of images.
